there seems to be a loop. I saw that some hooks are using the concept of being "mounted" something that doesn't work for some time in React 18. the two questions are, 1) is it possible to call removeObservers only if the parent is still there? b) is it being unmounted and removed without removing observers now?

I will try to add a ? here for example, but I'm not sure if it is only that or an edge case is happening?

return () => {
  mounted.current = false;
  observer.current?.removeObservers();
  observer.current = null;
};

Thanks
